Being young and naive and unfamiliar with the plant, when it germinated I didn't realize that it was no such thing. I allowed it to grow in its pot, flower, and seed into all the nearby pots. Turned out to be that pest of pests, Nothoscordum inodorum. And thanks to re- use of potting soil, it spread into the garden. The eradication campaign took ten years of careful digging with a fern trowel and a number of kettles of boiling water to destroy offsets near the holes I dug. These days I'm trying to eradicate Allium roseum from commercial bulbs that form innumerable bulblets below ground and bulbils in the inflorescences. I question if my garden will ever be entirely free of it. (Alliums grow very very well in Victoria's climate!) There is no universally valid moral to this story, except, perhaps, "beware the re-use of potting soil." -- Rodger Whitlock Victoria, British Columbia, Canada Z. 7-8, cool Mediterranean climate
